Answer:
1. a = 5, b = 8
2. d = 2
Step-by-step explanation:
1. The sum of two adjacent angles of a parallelogram is 180 degrees
Hence,
[tex]14a-5+115 = 180 \\14a = 180 -110\\a = 70/14\\a = 5[/tex]
Like wise
[tex]8b+1+115 = 180 \\8b = 180 -116\\8b = 64\\b = 8[/tex]
2.
The two intersecting diagonals cut each other into equal half
[tex]5d + 1 = 3d + 5\\2d = 4\\d = 2[/tex]
